Parameter descriptions for DISPLAY STGCLASS
- (generic-class)
-
Name of the storage class. This is required.
This is 1 through 8 characters. The first character is in the range A through Z; subsequent characters are A through Z or 0 through 9.
A trailing asterisk (*) matches all storage classes with the specified stem followed by zero or more characters. An asterisk (*) on its own specifies all storage classes.
- WHERE
-
Specify a filter condition to display only those storage classes that satisfy the selection criterion of the filter condition. The filter condition is in three parts: filter-keyword, operator, and filter-value:
- filter-keyword
- Almost any parameter that can be used to display attributes for this DISPLAY command. However, you cannot use the CMDSCOPE or QSGDISP parameters as filter keywords. You cannot use PSID as a filter keyword if you also use it to select storage classes.
- operator
- This is used to determine whether a connection satisfies the filter value on the given filter keyword. The operators are:
- LT
- Less than
- GT
- Greater than
- EQ
- Equal to
- NE
- Not equal to
- LE
- Less than or equal to
- GE
- Greater than or equal to
- LK
- Matches a generic string that you provide as a filter-value
- NL
- Does not match a generic string that you provide as a filter-value
- filter-value
- The value that the attribute value must be tested against using the operator. Depending on the filter-keyword, this can be:
- An explicit value, that is a valid value for the attribute being tested.
You can use operators LT, GT, EQ, NE, LE or GE only. However, if the attribute value is one from a possible set of values on a parameter, you can only use EQ or NE.
- A generic value. This is a character string (such as the character string in the DESCR parameter) with an asterisk at the end, for example ABC*. If the operator is LK, all items where the attribute value begins with the string (ABC in the example) are listed. If the operator is NL, all items where the attribute value does not begin with the string ABC are listed. Only a single trailing wildcard character (asterisk) is permitted.
You cannot use a generic filter-value for parameters with numeric values or with one of a set of values.
- An explicit value, that is a valid value for the attribute being tested.
- ALL
-
Specify this to display all the parameters. If this parameter is specified, any parameters that are also requested specifically have no effect; all parameters are still displayed.
This is the default if you do not specify a generic name, and do not request any specific parameters.
On z/OS this is also the default if you specify a filter condition using the WHERE parameter, but on other platforms only requested attributes are displayed.
- CMDSCOPE
-
This parameter specifies how the command is executed when the queue manager is a member of a queue-sharing group.
If QSGDISP is set to GROUP, CMDSCOPE must be blank or the local queue manager.
- ' '
- The command is executed on the queue manager on which it was entered. This is the default value.
- qmgr-name
- The command is executed on the queue manager you specify, providing the queue manager is active within the queue-sharing group.
You can specify a queue manager name, other than the queue manager on which the command was entered, only if you are using a queue-sharing group environment and if the command server is enabled.
- *
- The command is executed on the local queue manager and is also passed to every active queue manager in the queue-sharing group. The effect of this is the same as entering the command on every queue manager in the queue-sharing group.
You cannot use CMDSCOPE as a filter keyword.
- PSID( integer )
-
The page set identifier that a storage class maps to. This is optional.
The string consists of two numeric characters, in the range 00 through 99. An asterisk (*) on its own specifies all page set identifiers. See DEFINE PSID.
- QSGDISP
- Specifies the disposition of the objects for which information is to be displayed. Values are:
- LIVE
- This is the default value and displays information for objects defined with QSGDISP(QMGR) or QSGDISP(COPY).
- ALL
- Displays information for objects defined with QSGDISP(QMGR) or QSGDISP(COPY).
If there is a shared queue manager environment, and the command is being executed on the queue manager where it was issued, this option also displays information for objects defined with QSGDISP(GROUP).
If QSGDISP(ALL) is specified in a shared queue manager environment, the command might give duplicated names (with different dispositions).
In a shared queue manager environment, use
to list ALL objects matchingDISPLAY STGCLASS(generic-class) CMDSCOPE(*) QSGDISP(ALL)
in the queue-sharing group without duplicating those in the shared repository.name
- COPY
- Display information only for objects defined with QSGDISP(COPY).
- GROUP
- Display information only for objects defined with QSGDISP(GROUP). This is allowed only if there is a shared queue manager environment.
- PRIVATE
- Display information only for objects defined with QSGDISP(QMGR) or QSGDISP(COPY).
- QMGR
- Display information only for objects defined with QSGDISP(QMGR).
QSGDISP displays one of the following values:- QMGR
- The object was defined with QSGDISP(QMGR).
- GROUP
- The object was defined with QSGDISP(GROUP).
- COPY
- The object was defined with QSGDISP(COPY).
You cannot use QSGDISP as a filter keyword.
Requested parameters
Specify one or more parameters that define the data to be displayed. The parameters can be specified in any order, but do not specify the same parameter more than once.
- ALTDATE
-
The date on which the definition was last altered, in the form
yyyy-mm-dd
. - ALTTIME
-
The time at which the definition was last altered, in the form
hh.mm.ss
. - DESCR
- Descriptive comment.
- PASSTKTA
- The application name used to authenticate IMS bridge passtickets. A blank value indicates that the default batch job profile name is to be used.
- XCFGNAME
- The name of the XCF group that IBM MQ is a member of.
- XCFMNAME
- The XCF member name of the IMS system within the XCF group specified in XCFGNAME.
